What happened exactly with Universum ? Golovkin is a major talent and I cannot understand that.

Golovkin says his contract with them is over, Universum says it's not. Universum got an interim ruling in their favor a couple weeks ago, which is why they had to move the Tapia fight from Panama to Kazakhstan. They've had lawsuits with most of their top fighters over the last few years, but most of them settled (Sturm, Dzinziruk, Erdei, etc.)
